<p><P>PROBLEM TO BE SOLVED: To provide an electorphotographic device which can improve the durability of an electrophotographic photoreceptor and obtain an image free of a cleaning defect, image disorder, etc., in any environment throughout from the beginning till after the endurance. <P>SOLUTION: The electrophotographic photoreceptor has a photosensitive layer and a surface protection layer on a conductive base; and the surface protection layer contains 35.0 to 45.5 mass % fluorine atom containing resin particles for the total mass of the protection layer and is of 0.1 to 5.0μm in 10-point mean surface roughness, 0.1 to 10.0 in surface hardness by a Taber's abrasion resistant test method, and 0.1 to 0.7 in surface friction coefficient. A cleaning means is a rubber elastic body blade and characterized in that: the linear pressure of the blade to the electrophotographic photoreceptor is 0.294 to 0.441 N/cm; the glass transition point (Tg) of toner in use is 40 to 55°C; the tensile modulus (Young's modulus) as a blade property value is 784 to 980 N/cm<SP>2</SP>; the value of repulsive elasticity is 35 to 55%; and fluorine atom resin particulates are incorporated in the surface of the base material. <P>COPYRIGHT: (C)2003,JPO</p> |
